Activity Measure for Post-Acute Care "6-Clicks" Basic Mobility Scores Predict Discharge Destination After Acute Care Hospitalization in Select Patient Groups: A Retrospective, Observational Study.

Janet Herbold, Divya Rajaraman, Sarah Taylor and 2 others

PMID 36123982

WHAT IT FOUND

A standardized “6-Clicks” mobility score of 42.88 or higher predicted discharge to home rather than an institution for the overall sample and orthopedic, pulmonary, and other neurological groups.

The score failed to reliably distinguish home from home-with-services or inpatient rehab from skilled nursing.

Key findings

01A standardized Basic Mobility score cutoff of 42.88 predicted discharge to home (with or without services) versus an institution (skilled nursing or inpatient rehab) in the combined sample, with a positive predictive value between 0.84 and 0.87.

02The model failed to meet robustness criteria for distinguishing between home and home with services, or between inpatient rehabilitation and skilled nursing facilities, meaning these decisions cannot rely on the mobility score alone.

03Orthopedic patients had a lower initial cutoff score of 41.46 for predicting home versus institution discharge when scored closer to admission, suggesting they may be discharged home with slightly lower initial mobility scores than other groups.

What it does not show

The study excluded general medical and surgical patients, as well as those with amputations or spinal cord injuries, so the results do not apply to these common acute care populations. The data came from a single health system in New York, so discharge patterns and insurance factors may differ in other regions. The researchers could not determine the exact number of days post-admission when scores were taken, making it difficult to assess how recovery time influenced the scores. The analysis was limited to patients who had two mobility scores on record, which reduced the sample size and may have excluded patients with incomplete documentation.

Declared interests

The authors declared no conflicts of interest. The study was approved by the Institutional Review Boards of Albert Einstein College of Medicine and Hunter College of the City University of New York. Informed consent was not required due to the retrospective nature of the study.

The easy way to misread this

Do not use the “6-Clicks” score to decide between home with services and home without services, or between inpatient rehabilitation and skilled nursing facilities. The study found these specific comparisons did not meet the statistical threshold for robustness, meaning the score alone is not reliable for these finer discharge decisions.
